Escape from Graveyard Game

I always told you to get rid of this habit of yours... You know, the wandering around graveyards. Look where it led you... You spent too much time in there so the keeper of the graveyard locked you in accidentally. And now it's already dark and a storm is due to come. Well done... I hope you learn your lesson this time. Now start to think how you will get out of here. Find some tools and clues. Look underneath every stone, every pile of bones. There must be something. Wow that owl looks very angry. But maybe he can be some help too. Good luck!
